Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only a portion of received positioning signals or positioning signals received during a portion of position occasions are applied to obtain measurement results, then the processing complexity is reduced, but the measurement accuracy and reliability deteriorate
Solution Approach 1:
The patent combines multiple measurement results obtained from different position occasions to generate a final measurement report. Instead of using only a portion of positioning signals, the system aggregates measurements from all available position occasions, thereby improving measurement accuracy and reliability while managing processing complexity through systematic combination methods.
2Measurement precision
If all received positioning signals from multiple base stations during multiple position occasions are used for measurement, then the positioning accuracy is improved, but the measurement reliability deteriorates due to potential incorrect results
Solution Approach 1:
The patent implements a feedback mechanism where measurement results from multiple position occasions are evaluated and combined systematically. The system uses the measurement results to generate a final measurement report that reflects the most reliable positioning information, effectively filtering out incorrect results while maintaining high positioning accuracy through iterative measurement and combination processes.
